Bcl6 Suppresses Cardiac Fibroblast Activation and Function via Directly Binding to Smad4.
Article in Current medical science, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bcl6, a critical pro-oncogene of human B-cell lymphomas, can promote tumor progress. Previous studies have found that Bcl6 participates in hypoxia injury in cardiomyocytes. However, the effect of Bcl6 on cardiac fibroblasts is still unclear. The aim of this study was to elucidate the functional role of Bcl6 in cardiac fibroblast activation and function. The neonatal rat cardiac fibroblasts were isolated and cultured. First, transforming growth factor ß1 (TGFß1) was used to stimulate fibroblast activation. A decreased expression level of Bcl6 was observed in fibroblasts after stimulation with TGFß1. Then, cells were transfected with adenovirus Bcl6 to overexpress Bcl6. The results showed that Bcl6 overexpression induced decreased proliferation and reduced activation of fibroblasts which were stimulated with TGFß1. It was found that activated smad2 and smad3 were not changed by overexpressing Bcl6, but smad4 was decreased. Furthermore, co-immunoprecipitation results showed that Bcl6 directly bound to smad4, and induced down-regulation of smad4. At last, smad4 activator could counteract the anti-fibroblast effects of Bcl6. In conclusion, Bcl6 may negatively regulate cardiac fibroblast activation and function by directly binding to smad4.
